CARRIAGE-SPRING.

SPECIFICATION forming part of Letters Patent No. 427,261, dated May 6, 1890. Application filed March 1,1890. Serial No.34=2,230. (No model.)

To all whom it may concern.-

Be it known that I, WALTER T. FOSTER, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Carriage-Springs, of which the following is a specification.

This invention relates to an improved spring for side-bar vehicles, by which a higher degree of elasticity is imparted to the carriage-body, and the same subjected in a lesser degree to the jolts or concussions caused by the pavement.

In the accompanying drawings, Figure 1 represents a rear view of a side-bar vehicle with my improved springs attached thereto. Fig. 2 is a bottom view of the springs drawn on a larger scale. Fig. 3 is aside elevation, partly in vertical section; and Fig. 4:, a vertical transverse section on the line 2 2, Fig. 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a spring consisting of a looped leaf. The upper end of the leaf of springA extends diagonally outward and is attached to an elastic cushionplate B, which is secured to the bottom of the carriage-body, as shown clearly in Fig. 1. The loop A is formed at the inner end of the spring near the inner end of the leaf. The middle part of the leaf, constituting the spring are united to the main leafby a fastening bolt or rivet d. The lower end of the spring A is applied by a shackle e to the side bar of the carriage-body. The spring is guided by a recessed guide-lug, which is attached to the bottom-plate B, said guide-lug being provided with a recess f, engaging the spring, and preferably with a concavity f for the head of the bolt or rivet d, so as to permit the play of the same in following the motion of the spring without coming into contact with the guide lug f. The guide-lug f engages the looped part of the spring and serves as a steadyingguide for the looped end of the spring A. Two

springs are applied to each bottom-plate B, said springs extending symmetrically from the same to the side bars. The springs are arranged at each end of the carriage-body,

said springs having the advantage of resisting in a high degree the joltin g action exerted by the pavement on the carriage-body and neutralizing the concussions to which the same is subjected, so that a better and more comfortable riding of the body is obtained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of a follower-plate provided with guide-lugs, and looped springs, the loops of which are engaged by said guide-lugs, the inner ends of the leaves of said springs extending in outward direction and being attached at diagonally-opposite points to said plate outside of said guide-lugs.

2. The combination ofa follower-plate provided with centrally-disposed recessed guidelugs and with cushions at diagonally-opposite points, and looped springs, the loops of which are engaged by said guide-lugs, the inner ends of the leaves of said springs extending in outward direction and being attached to said cushions, substantially as described.

3. The combination of a follower-plate provided with centrally-disposed recessed guidelugs and with cushions at diagonally-opposite points, and looped springs, the loops of which are engaged by said guide-lugs, the inner ends' of the leaves ofv said springs extending in outward direction and being attached to said cushions, and the central portions of said leaves being provided with shorter re-enforcing leaves,substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

WALTER T. FOSTER.
